And your results were...? Or did you use a software adjustment?wombat778 said:I did a very nice calibration of the colors using Adobe Gamma and the test pattern at the following site:

Using my Pantone Colorvision USB color calibration unit, here are the settings I came up with for my particular unit. YMMV based on manufacturing variability, but for those without a calibration unit this is probably a good start.
Since this is supposedly an sRGB compliant monitor, normally just setting sRGB should be perfect, but that wasn't the case. These settings work much better:
(target sRGB 6500K of course)
Brightness 27
Contrast N/A (not available in DVI)
Color: User Preset
Red 36
Green 33
Blue 32
With any brightness setting the gamma was still too low (i.e. too bright) around 1.89. I solved this by using the nVidia driver color adjustment page to set the gamma slider to 0.91 which gave me a measured gamma of 2.05. This is still a touch brighter than sRGB but I couldn't get it any higher, and as the page below notes, 2.0 is a good compromise between Mac (1.8) and PC (2.2) gamma.

chrism said:Two things about Adobe Gamma:
1) It says the hardware White Point is set to 5000K and the adjusted White Point is "Same as hardware". Shouldn't the hardware White Point be set to 6500K? Should I change the hardware White Point through Adobe Gamma? Should I change the adjusted White Point through Adobe Gamma?
2) Why when I load a new profile, does it not make any changes to the screen settings? It only seems to do anything when I actually change something. I would think just loading a different profile would immediately show the changes.
wombat778 said:The listed "hardware whitepoint" is the whitepoint as listed in the profile you are using, unless you you use the measurement tool which is pretty innaccurate. It probably lists the whitepoint as 5000K because you are using the wrong profile.
In terms of the changes you see, this is where it gets kinda confusing. ICC profiles can contain two types of information - color calibration information, and color profiling information. Adobe Gamma only deals with the calibration information, NOT the profile information. It helps you load and adjust the gamma setting that get loaded into your video card's LUT tables. This will affect the way all windows applications, and the windows desktop looks. An ICC profile can also contain profiling information, which only gets used by ICC aware applications such as Photoshop. My guess is that when you are loading a "new" profile, you are loading one that only contains profiling information, but does not contain calibration information. This is why you dont see any difference until you modify the gamma settings (thereby adjusting the calibration information).
Confused yet
chrism said:So I assume then that the Whitepoint setting is used only by the color profiling (which is only used by ICC-aware apps like Photoshop, which I do have)? Therefore, should I set the hardware Whitepoint to 6500K and the adjusted Whitepoint to "Same as hardware"?

Terpfen said:Thread bump and question.
I'm not running a 2405FPW, but I wanted to avoid making an unnecessary thread. I'm unsure about proper LCD calibration, here--I keep reading about people who set their brightness and contrast low, and their RGB settings equally low (or set at 6300K), but when I attempt to duplicate that, my monitor is dark to the point of being unable to see anything. What am I missing here?
Riptide_NVN said:The settings msny posted work very well. And the adjustment page he linked to proved it to me.
EnderW said:there's still something bothing me about this screen
I don't know how to describe it...it's just not easy on the eyes
I have the brightness down to like 15 and I've tried various sRGB settings
thinking of trading my 6800U for an ATI card since they're supposed to have better pic quality
don't know what else to do
